16 Result (or replicate) has been deleted. (F1)
17 The dark measurement was higher than the test measurement. (F3)
18 The values near the endpoint fluctuate. (F3)
19 The result from the parallel or perpendicular measurement was inconsistent. Air bubbles in the sample
may be the cause. (F3)
20 The measured absorbance is higher than 2.0. (F3)
21 High Activity. The absorbance change during measurement exceeds the accepted limit, i.e . the reaction
has taken off too fast. Possibility of substrate exhaustion. %1% = [value] - is Test Range High (F3)
22 High Background.Background fluorescence (noise) from the sample may interfere with FP
measurement. (F3)
23 ISE Measurement Unstable. The mV values from the electrode are not stable. The following problems
may have occurred: - Air bubbles in measuring segment. - One or more sealing rings is missing or
damaged. - Electrode has not been serviced. - Expiry period of the electrode has been exceeded or the
electrode is damaged. - Preamplifier is not working properly. (F3)
24 The intensity obtained in the parallel or perpendicular measurement is insufficient. (F3)
25 The sensor could not detect any liquid. Either the liquid has not been pipetted, the pipetted sample was
lipemic, or the ISE tubing was blocked. (F3)
26 The sensor could not detect a calibrator. ISE Calibrator bottles are not available or the tubing is blocked
or leaking. (F3)
27 Unable to calculate the kinetic change. Either change is not stable (Kinsearch) or "non-existent"
(Kinetic). The first and last part of the reaction have very different slopes. (F3)
28 Curve is not monotonic (constantly decreasing or increasing). Curve cannot be calculated. (F3)
29 Calibration curve or slope does not fall within programmed range. (F3)
30 Too many outliers occurred in the parallel or perpendicular FP measurement. Air bubbles in the sample
or electronic noise may be the cause. Recommended action: Repeat the measurement with a sample
free of bubbles; Inform Roche Service is flag appears again. (F3)
31 The parallel measurement was higher than the perpendicular measurement. Recommended action:
Repeat the measurement. Inform Roche Service if flag appears again. (F3)
34 Result (or a replicate) is erroneous or corrected. Result has been accepted.Recommended action: Check
results reaction curve to establish the cause of the deviation; repeat sample measurement. (F1)
35 Result (or a replicate) is erroneous or corrected. Result has not been accepted.Recommended action:
Check results reaction curve to establish the cause of the deviation; repeat sample measurement. (F1)
36 No end of sample segment detected. It takes too long for a sample segment to reach the electrode
assembly. The tubing may be blocked or leaking. (F3)
37 No end of calibrator segment detected. It takes too long for a calibrator segment to reach the electrode
assembly. This may be due to the lack of calibrator or the tubing may be blocked or leaking. (F3)
38 The solution 1 factor is outside the acceptable range. (F3)
63 Result obtained after a repeated run. (F1)
71 New calibration overwritten with old accepted calibration
255 Any Calibration-Flag.
